研究目的: |
1. 探究不同数字媒体形式(短视频、娱乐直播、科普视频)的使用与大学生认知功能、心理健康及生活方式(睡眠、饮食、身体活动)之间的关联; 2. 量化比较不同数字媒体形式对认知表现、主观情绪及自主神经反应的即时影响; 3. 考察睡眠、身体活动、饮食等生活方式因素在上述关联中的作用。 |

|
Objectives of Study: |
1. Investigate the association between the use of different digital media formats (short videos, entertainment livestreaming, science popularisation videos) and university students' cognitive functions, mental health, and lifestyle factors (sleep, diet, physical activity); 2. Quantitatively compare the immediate effects of different digital media formats on cognitive performance, subjective mood, and autonomic nervous system responses; 3. Examine the role of lifestyle factors such as sleep, physical activity, and diet in the aforementioned associations. |

Agreement to avoid alcohol, caffeine and energy drinks for 24 hours prior to each experiment, and to avoid strenuous exercise for 2 hours prior to the experiment; 5. Digital Media Use: To maintain ecological validity, regular users of digital media are not excluded. However, it is required that the average daily total recreational screen time (including short videos, live streaming, social media, gaming, etc.) over the past month has been between 1 and 6 hours, to avoid including individuals with extremely low or extremely high exposure; 6. Compliance: Able and willing to arrive at the laboratory at the designated time in accordance with the study protocol to complete the entire experimental procedure, and to cooperate with the wearing of relevant monitoring devices. |
